Paulo S.L.M. Barreto

Paulo S. L. M. Barreto is a Brazilian cryptographer and one of the designers of the Whirlpool hash function and the block ciphers Anubis and KHAZAD, together with Vincent Rijmen. He has also co-authored a number of research works on elliptic curve cryptography and pairing-based cryptography, including the eta pairing technique, identity-based cryptographic protocols, and the family of Barreto–Naehrig (BN) pairing-friendly elliptic curves. More recently he has been focusing his research on post-quantum cryptography, being one of the discoverers of quasi-dyadic codes and quasi-cyclic moderate-density parity-check (QC-MDPC) codes to instantiate the McEliece and Niederreiter cryptosystems and related schemes.
